GRAIN CLEANER AND SCOURER.

SPECIFICATION forming part of Letters Patent No. 647,990, dajsed April24, 1900. Application filed September 6, 1899. Serial No. 729,643. (Nomodel.)

To @Mw/tom t may concern.:

Beit known that LWILLIAMW. SALISBURY, a citizen of the United States,residing at Berea, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Grain Cleaners andScourers, of which the following is a specification.

My invention relates to grain cleaners and scourers; and the object isto provide a simple and effective apparatus which will revolveautomatically as the grain is fed to it.

The construction of the apparatus will be f ull y described hereinafterin connection with the accompanying drawings and its novel featuresdefined in the appended claims.

In the drawings, Figure l is a side elevation, partly in section, of agrain scourer and cleaner embodying the invention; and Fig. 2 is a planview of the hopper. y

The reference-numeral 1 designates a shaft, preferably consisting ofgas-pipe and having its ends provided with journals 2, supported insuitable bearings 3. Secured tothe shaft 1 are two spirally-disposedtroughs 4 and 5, made ofwire-netting or like screen material bent tosemicircular form in cross-section and twisted spirally around the shaft1 from opposite sides thereof. These troughs 4 and 5 are secured to theshaft 1 by transverse bracerods 6, formed centrally with a sleeve 7. Theshaft 1 extends through the sleeves 7, and the latter are held upon theshaft by set-screws 8. The ends 9 of the rods 6 are curved to embracethe troughs, as shown. The lower ends of the spiral troughs areconnected by a short Sleeve 10, with which the troughs communicate andthrough which the shaft 1 extends, the sleeve being of sufcient diameterto permit the grain to pass through it freely to a bin 11. The upperends of the troughs are secured to a hopper 12, which is of cylindricalform and provided with a central opening for the shaft, to which thehopper is keyed or otherwise firmly secured. The hopper is dividedcentrally by a vertical partition 13 and formed with discharge-openings14 and 15 at opposite-sides of the hopper and partition. These openings14 and 15 permit the grain to feed from the hopper into the troughs. Tofacilitate this feed, the compartments of the hopper are provided withoppositely-inclined causes the latter to revolve, carrying with them thehopper and brace-rods 6. The revolving motion and the irregular path ofthe grain as it passes through the troughs result grain as it fallsagainst the sides of the troughs in an agitation of the grain, whicheffectually scours and cleans it, the cleaned product being deliveredthrough the discharge sleeve or spout 10.

I claim- 1. A grain scourer and cleaner comprising a revoluble verticalshaft; spirally-disposed troughs secured to said shaftto revolvetherewith 5 and a revolving hopper secured to said shaft and troughs.

2. A grain scourer and cleaner, comprising a revoluble vertical shaft;spirally-disposed troughs consisting of wire-netting or equivalentscreen material secured to said shaft; a hopper secured to the upperends of the troughs; and a receiving-receptacle at the lower ends of thetroughs, said troughs being adapted to revolve by the Weight of thegrain fed to them from the hopper.

3. In a grain scourer and cleaner, the combination with a revolublevertical shaft; of a hopper secured thereto; spirally-disposed troughssecured to the shaft, and communicating with t-he hopper; and adischarge-spout secured to the lower ends of the troughs.

4. In a grain scourer and cleaner, the combination with a revolublevertical shaft, of a hopper secured thereto, and provided withoppositely-arranged feed-openings; spirallydisposed troughscommunicating with the openings in the hopper; a series of transverserods securing the troughs to the shaft; a discharge spout or sleeveconnecting the lower ends of the troughs; and a bin or receptacle belowsaid discharge-spout.

In testimony whereof I affix my signature in presence of two witnesses.

WM. W. SALISBURY.
